Redistricting in the United States is the process of drawing electoral district boundaries. The Uniform Congressional District Act (enacted in 1967) requires that representatives be elected from single-member districts. Six states — Alaska, Delaware, North Dakota, South Dakota, Vermont, and Wyoming — with only one seat each because of their low population do not need redistricting for the House and elect members on a state-wide at-large basis. Redistricting is a contentious political process since the results may determine which political party controls the house of representative.
